[SOLVED] DDLC won't run under Wayland

Idk if this applies to every Ren'Py game under a specific version, but yeah. DDLC will not run under Wayland. Even after added "GDK_BACKEND=x11", it still won't run. Here's the log (Using Purist Mod, but the vanilla game have the same issue.):

I'm sorry, but an uncaught exception occurred.

While running game code:
  File "renpy/common/00start.rpy", line 188, in script call
    call _gl_test

Another Ren'Py game, Katawa Shoujo Re-Engineered, run perfectly under Wayland. I have XWayland instakked too, in case you ask. Also, Danganronpa 2 also won't run under Wayland for some reason, Danganronpa 1 run just fine

Re: [SOLVED] DDLC won't run under Wayland

Ok, managed to fix DDLC by add SDL_VIDEODRIVER=x11. Danganronpa 2 though, here's the log

QT_DEBUG_PLUGINS=1 ./Launcher
QFactoryLoader::QFactoryLoader() ignoring "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3" since plugins are disabled in static builds
This application failed to start because it could not find or load the Qt platform plugin "wayland;xcb".

Available platform plugins are: xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

Already have both libxcb and lib32-libxcb installed, btw

Re: [SOLVED] DDLC won't run under Wayland

Try to set QT_QPA_PLATFORM=xcb as well.
